  • In these companies, does anyone check the licenses in details to make sure using them is ok for the company?

    Meta will get at least the metadata: meaning they will record who was in which call connecting from where.

    For example, if one member is visiting a client, Meta may be able to infer the relation between the 2 companies.

    If any of the people in the room click “report”, then the discussion is sent for review without the encryption protection

    I’m pretty sure their user agreement translates to “you agree to let us do whatever the f*ck we want with the data you’re purposely disclosing to us”.

    And last but not least: if Meta decides to wipe the archives, any info get lost?

    There a reasons large companies ban unauthorized apps to talk about work.











  • Nuclear plants consist mainly of a shitton of concrete (and only the best sort is good enough). The production of that concrete causes a terrible amount of carbon emissions upfront.

    Actually, if you compare them to solar or wind at equivalent service, it’s not that straightforward:

    Renewables installed capacity is nowhere close to their actual production, nuclear can produce its nominal capacity in a very steady way.

    Wind turbines also need a lot of concrete, and much more metal for equivalent output. Solar panels need a lot of metals.

    Renewables need a backup source to manage their intermittency. It’s most often batteries and fossil plants these days. I don’t think I need to comment on fossil plants, but batteries production also has a very significant carbon emission budget, and is most often not included in comparisons. Besides, you need to charge the batteries, that’s even more capacity required to get on par with the nuclear plant.

    With all of these in consideration, IPCC includes nuclear power along with solar and wind as a way to reduce energy emissions.





  • “Collapse” meaning what, exactly? Do you mean run out of storage from the volume of content, or that processing all the messages is too taxing?

    Years back, I setup a Synapse’s server on my personal server (Yunohost). At some point, I joined the “big” Matrix room. Bad idea: RAM and CPU usage went through the roof. I had to kill the server but even that took forever as the system was struggling with the load.

    But don’t just take my words for it:

    https://github.com/matrix-org/synapse/issues/7339

    Last comment is from less than one year ago. I was told things should be better with newer servers (Dendrite, Conduit, etc.), but I’ve not tried these yet. They’re still in development.

    How does it scale differently than Matrix?

    The Matrix protocol is a replication system: your server will have to process all events in the room one or more users attend(s) to. There is a benefit to this: you can’t shut down a room by shutting down any server: all the other ones are just as “primary” as the original. Drawback: your humble personal server is now on the hook.

    XMPP rooms are more conventional: a room is located on one server. That’s an “old” model, but it scales.

    https://www.ejabberd.im/benchmark/index.html

    That’s for the host. For other attendees, it’s much lower.

    I don’t think I atteld any public room out there with 3k users, so I can’t report my first hand experience, this is the best I found. But I never had to check for load issue on a small server (running Metronome and many more services).

    Out of curiosity, why do you say this?

    I don’t use the Fediverse the way I engage with individual people. If I want a closer relation with someone, I don’t want to be bound to yet-another-messenging system, let alone on multiple accounts

    And another reason is I may not want to be bothered by people I don’t know, regardless how much I could appreciate reading and/or exchanging with them in the Fediverse.

    Ignoring or declining requests from strangers can leave a lot to interpretation and then frustration. Remove the button and no one is tempted to press it the be disappointed with the outcome. Less drama.

    And that’s only considering well intended people.

    But these are my humble 2cents.



  • What I don’t like with Matrix is the load it puts on the server. It basically copies 100% of a room content to any server having one or more users registered in the room.

    So if you’re on a small server, and one user decides to join a 10k+ large room, your server may collapse under the load as it tries to stay in sync with the room’s activity. This is deterrent to self-hosting or family/club/small party servers.

    XMPP, on the other hand, has proven to be highly scalable, has E2EE, federation and some bridging services.

    The only thing XMPP does NOT have is a single reference multiplatform client with all basic features for 2023 (1:1 chat, chat rooms, voice/video 1:1, and voice/video conference) than anyone can use without wondering if the features-set is the same as the persons you’re talking to.

    And while we’re there: I’m not even sure I want a messaging account linked to any of my Fediverse accounts…

    Sorry to ruin this dream, but not a single developed country (and most likely not a single non-developed either) has a remote chance of being carbon neutral in 10years.

    Reason number one is “carbon-neutral” is yet another greenwashing marketing idea involving emissions compensations that are just not there.

    We’ve seen now that planting trees will probably not do any good: we already see trees growing failure rate increasing due to excessive heating. They grow slower already, making all compensation calculations wrong, and they’ll burn in wildfires in summer, releasing all the carbon they captured.

    The second reason is the insanely high dependency we have to cheap oil. You need to convert haul truck, small trucks, buses, etc. to electric all while you turn the grid to 0 emission.

    You need to convert cargo ships to electric otherwise your net neutrality will need to conveniently ignore all importations and exportations.

    You need to convert all farm machines to 0 emissions and abandon quite a lot of the chemistry considered for granted today, which means yields will drop.

    You need to convert blast furnaces to alternative energies. Today, there is almost nothing done there other than “we’ll get hydrogen” that everybody know cannot be produced in the volume they need, let alone at an acceptable price.

    And no energy source whatsoever is carbon neutral!

    Solar panels need quite some metal and semicon-based manufacturing techniques. Wind farm need concrete for their anchoring, and use advanced materials to build. They both have a limited lifespan, after which you need to recycle (By the way: noticed that when “recycling” is advertised, no one mentions if it’s rectcling for the same usage and not recycled to lower grade material we can’t use back to produce the same device? That’s because we just can’t get them back with the same purity level…) and make some replacement, that will again have a share of emissions.

    Short of producing absolutely everything in the chains of supplies locally, you will import emissions from another country

    Any human activity is basically emitting or causing greenhouses emissions.

    And while you think all of that can be managed, we already have all signals to red on the natural resources: we can’t extract lithium fast enough, and we may not want to given how dirty the mines are. We may run out of some metals we rely on.

    And most of these issues are eluded in the great plans, because it’s too complicated or we simply have no solution and no one wants to say it up and loud.

    Now, the good/bad news: all of this will end because we’re also running out of cheap oil.

    It’s a good news because that will put a break in humans activities and so greenhouse gas emissions.

    But it’s bad because not a single country is preparing for the aftermath, and that means… they will collapse!


  • All bills targeting your freedom are labelled “child porn” or “terrorism”.

    After terrorists attack in France, state of emergency was declared, special powers to restrainesuspicious powers at home. We MUST protect people frometerrorists, right? If you’re against that, which side are you on? Very first usage of the power: restrain non-violent eco-activists to their home so that they don’t disturb the COP.

    That pattern repeats over and over. They’re counting on you being sensitive to “child porn”, I bet you the initial list will include “eco-terrorists” sites (label used on anyone attending a climate protest they tried to prevent), political activists sites (you try to be anonymous on Internet? That’s SO suspicious!).

    I’m sorry for what happened to you, but ri seriously doubt this bill is really intended to prevent that.
